LUBRICATING DEVICE.

Application lled November 21, 1923. Serial No. 676,145..

T all whom t may concern:

Be it known that I, PALEMON H. GAsKINs,

a citizen of the United States, residing at Jacksonville, in the county of Duval and State of Florida, have invented certain new and useful Improvements in Lubricating Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to lubricating devices1 and has for its object to improve the constructions heretofore proposed.

Wfith this and other objects in view, the invention consists in the novel details of construction and combinations of parts, as will be more fully hereinafter described and particularly pointed out in the claims.

Referring to the drawings, forming a part of this specification, and in which like numerals designate like parts inall the views:

Figure 1 is a diagrammatic view partly in section showing the invention as applied to the sp-ringsuspension of an automobile;

Figure A2 is a sectional View taken on the line 2-2 of vFigure 1,v and looking in the direction of the arrows; y

Figure 3 is an enlarged sectional view of so-me o-f the parts shown in Figure 2;

Figure 4 is a View' similar to Figure 2 showing a modification of the invention; and

Figure 5 is an enlarged partial view of one of the parts shown in Figure 4.

This invention is an improvement over the construction disclosed in my Patent #1,433,612 granted October 31, 1922.

In the drawings, 1 indicates the usual channel forming a side frame member of the chassis of an automobile. Passing through the ldepending flanges 8 of the channel 1 is the upper shackle bolt 2 provided 45 as usual with the sleeve 3 and the shackle links 4 and 9. The lower shackle bolt 5 passes through the turned over end 6 of the vehicle spring 7, and is supported by the said links 4 and 9, all in the manner well 50 known, and shown in Figures 1, 2 and 4.

10'v indicates any suitable pipel or other conveying means adapted to carryoil or other lubricant to the movable parts of the vehicle. As shown in Figurel, the pipe 10 is conveniently located within the channel frame member 1 and is tapped as by the branch or nipple 11 adapted to furnish the said oil to the upperv shackle bolt 2 and its sleeve 3. This is accomplished by securing one end of the nipple 11 in the bore 12 of the sleeve 3 in any well known suitable way. Preferably the said bore 12 is located equidistant the ends of the sleeve 3 in order to obtain equal lubrication. y

It is well known that any `lubricant in a bearing of this character will seep out at the ends of the sleeve 3, 'and run down the adjacent surfaces before its lubricating qualities have been entirely used. Therefore, it is the purpose of this invention, when more specifically stated, to overcome this wasteful, as well as objectionable, condition by putting to use this only partly spent oil or lubricant which would ordinarily escape.

To this end one of the shackle links such as 4 is provided with the pocket'15 having its bottom inclined downwardly as clearly shown in Figure 3. The pocket 15 is further so formed in the link 4 that the outer` edge 16 ofsaid pocket is slightly below the bore 17 through which the bolt 2 passes.

From the foregoing, it will now be seen that oil in pipe 10 will pass through the nipple 11 and form a thin lubricating 'film in the bearing 18 formed by the shackle bolt 2 and the sleeve 3. When the film of oil reaches the end of the sleeve 3 it will flow downwardly and seek an escape through the joint 19 between the sleeve 3 and the shackle link 4. But in so doing a portion of the said oil will be caught by the outer edge 16 of the pocket 15, and be directed into the said pocket along the inclined bottom thereof. j

The pocket 15 is connected as by the pipe or passage 2O (see Figure 2) to a pocket 21 similar in every respect to the said pocket 15 and formed in the link 4 at the bore 22 taking thevlower shackle bolt 5. Thus the oil collecting in pocket 15 will pass downwardly through the said `tube or passage 2O into pocket 21 and out to the bearing 23 formed by the lower shackle bolt 5 and the turned over end 6 of the vehicle spring 7. Tn this manner it will thus be seen, lubricant which would ordinarily escape from the upper shackle bolt bearing is collected and again used to lubricate the lower shackle boltl bearing.

ln the modified form of the invention shown in lligures '1l and 5, instead of the pockets l5 and 2l and the tube 20, all carried by the shackle link 4, l provide a separate link member 24- comprising a web or shank 25 connecting heads 26 and 30. rlhese heads 26 and 30 are alike in every respect and each is transverselybored as at 27 to receive the shackle bolts 2 and Passing through the web 25 of this linkfmember 2 and connectinglv the bolt bores 27de a'passage havingits extremities flared orenla-rged as at'29 to provide vapocket or lead for the oil. Thus'it will be seen that oil from'the supply pipe `l() will pass-throughfthe'nipple 11; lubricate the bearing.;v 18 formed-by the shackle bolt 2, and its sleeve 3, and `flow tofthe extremitiesof thebearing', all'in the manner as is well known. But inso passing to the said extremities of the bearing, a portion ofthe oil will enter the'flared-'end 29 of the'passage QSand flow liroufrh the said passage andfout the other end thereof into the bearing' ofthe lower shackle bolt It will now beseenthat ineach of the forms of this invention, l am enabled to avoid boringl axially andradially the shackle bolts 2 and 5, for'the conduction of oil becausesaidoil is led directly through the bearing, 3 to the bolt 2 and through the inner bore or'bearing of the link el or 245 to the surface of Vthe bolt 5. thereby also avoid the difficulties heretofore encountered in-connecting the axial passages thus produced in saidbolts. lnstead of this former constructioml employithe connections 20 or 28 between the outsidesurfaces of said bolts 2 and 5, as well as thepockets 15 and 2l. or flared ends or pockets 29, andam thus enabledto'usethe same oil twice.

V,lt is obvious that-those skilled in the art may vary the details ofconstruction as well as the arrangements of parts without departing` from the spirit of the invention, and therefore l do-not wish to be limited to the above disclosure except as maybe required bythe claims.
